Specification of Letters Patent. Patented Aug. 3, 1920.

Application filed April 1, 1916. Serial N0. 88.264.

T`aZZ whom t may concern: Be it known that I, WILLIAM M. Hormo- WAY, a citizen of the United States, residing in Maywood, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Listing-Adders, of which the following is a specification. I

The invention relates to adding machines; and to such vmachines having means for printing or listing the amounts registered, and to means for totalizing or printing at any time the sum of the amounts registered; with a view of effecting economy in the construction of the machine and convenience, rapidity and accuracy in its use; and the invention consists in the parts and combinations thereof hereinafter set 'forth and claimed.

In order to make the invention l, more clearly understood I have shown in the aecompanying drawings means for carrying it into practical effect, without limiting my improvements,.in their useful applications, to the particular construction which, for the purpose of example, I have delineated.

rotate their register wheels.; carrying mechanlsm or transfer devices for the register wheels; clearing or canceling means whereby the register wheels may be reset at zero; means for disconnectlng the ordinal4 mechanisms from the actuating means; printing devices whereby any number reglstered is l'o o printed when it is added; totalizing mechanism by which the sum of the numbers which have been added or the total showing of the register wheels may be printed at'any time; and means for cutting-out or eliminating from such totalizing any number which has been erroneously set up and ought not to be included in the registration or in the total. The various parts of the mechanisms are mounted within a suitable casing or outer shell 20, and within the outer shell or casing i is mounted a frame 23, adapted to support the several parts. In most of the figures the side and rear portions of the said casing, which I prefer to employ, have been omitted from the drawings to better display the mechanism. The machine illustrated comprises seven orders, although itv will be understood that the number of orders may be increased or diminished, as desired, by duplicating or omitting parts of some of the mechanisms, and inasmuch as a great many ofthe elements employed in each order or column are identical, I shall only describe the parts necessary for one order or column except in so far as it may be necessary to describe elements which are common to all of the orders of the machine.

`Primeactuating mechanism-Each order of the machine.` comprises a register or indicating wheel 24, having a gear (Fig. 5) and a ratchet 26, the'gear meshing with a vmajor gear 27, which, as' shown, is in the form of a disk, and has formed integral therewith a ratchet 28 (see Figs. 7 and 10), said gear 27 beingrotatably mounted on--a central, oscillatable shaft 29 extending transversely of the machine near the front of the same. 29 adjacent each major gear 27 is a set-up lever 30, which, as more clearlyV shown in j Figs. 6 and 23, is in the form of a disk having .one or more integral spring 31 each having a bent end 32, thelatter being adapted to serve as' a pawl and cooperating with the lratchet 28 to actuate the gear 27. The set-up lever 3 0 is provided with an arm /322L which projects through the slot in the finger-board 33 in the outer shell or case 20, said arm 321% having detachably secured thereto a iinger-hold 34 contiguous with which the operator may see the numerals on the finger-board 33. This fingerboard con- .,struction is fully' described in the patent iS- 'sued to Harbeck, No. 1036614 dated August 27, ,1912. The disk of each set-up lever is provided with a notch 36 over which is' normally positioned, when the set-up lever is at normal, an offset arm 37 (Fig. 6)hav ing a cam o1" incline 372L formed on the spring-controlled clearing bar vpawl 38, pivotally mounted on the shaft 39,.the latter serving also as the supporting shaft for the register wheels. The amount added in each order is determined bythe extent to which Also rotatably mounted on the shaft 4rod 64. When the set-up lever is raised the clearing bar pawl 38 will be lifted, owing to the cam face 37@ thereof being engaged by the corner 39 of the set-up lever, and the pawl 38 will in turn lift the clearing bar 41. The latter is pivotally mounted on the rod 42 extending across all the orders of the machine and rigidly mounted inthe combined prime-actuating, carrying, canceling, and printing yoke part or frame 43 (Fig. 5). The latter is preferably pivotally mounted on the shaft 29, and has an outwardly extended arm 44 to which is secured 85 the operative handle 45. Vhen the clearing bar 41 is thus raised, a projection 46 thereon will ride over the outside of a cam track 47 (Fig. 4) which prevents the clearing of the machine, as will be hereinafter described, this lifting of the clearing bar occurring by the raising of any set-up lever. When a set-up lever or levers have been set to the amount desired to be added, and the clearing ing the major gears`27,' which in turn actuate the register wheels each forman amount corresponding "to .thedistance. for which its set-uplever has been raised. When the oscillata'bleyoke or frame 43 is returned to its normal or upright positiomby hand ,or

by mea-ns of the reciprocating spring 43, v (Fig. 10) or spring 43" (Fig. 2), the plate 48, which yis provided with a plurality of` ,115 projections 49 on its rear edge, one for each order, willengage the ratchet's26 of the register wheels (Fig. 5) and center the same so that the numerals or other indicating marks will be properly alined with the apertures 50 in the casing (Fig. l), through which apertures the amounts indicated on the register wheels are adapted to be read. Said projections 49 in coperation with the clearing bar pawls 38 also serve another im- 126 portant function. As shown in Fig. 6, each clearing lbar pawl has a cam face 38L which is engaged by a projection 49 when the latter returns to normal, which causes the clearing bar pawl t0 be raised to 'neutral or normal 13V' position, as shown in said figure. When,

i however, the yoke 43 is moved from normal i. now more particularly to Figs. 6 and 8 it will be seen that rigidly secured to each of the major gears 27 is a disk 51 (Fig. 25)

`provided with a plurality of projections 52,.

the number of said projections corresponding with the number of teeth on the major gear. (in the sense that their number is a factor of the number of said teeth), there being inthe case illustrated one of such projections for each ten teeth of the gear. As each gear 27 is rotatedan amount corresponding to ten units, one of said projections 52 will engage the upper inner side of an offset 53 made integral With a springt controlled gate-actuator 54. The latter is pivotally mounted on a transverse rod 55. The ,said gate-actuator 54 has provided therein a T-shaped slot 56 through one portion of which extends a. transverse rod 57 on Which are mounted the transfer Wheels, each transfer Wheel comprising a ratchet disk 58 and a gear 59 (Fig. 29), the latter engaging (Figs. l() and 29) with a major gear 27 of the next succeeding higher order or column than that in Which the gate-actuator disk is located. y and adjacent the transfer wheel is a gate 60 (Fig. 27) having a pin 6l Which engages in another portion of said T-shaped slot 5G. When the parts are at normal, the

gate-actuator 54, transfer wheel and gate are in the position shown at the lower part of Fig. 6, but upon one of the projections 53 engaging the gate-actuator the parts are moved so as to cause the gate 60 to be oscillated on the shaft 57, saidgate 6U when in normal position closing an opening or recess 62 formed in a bracket or guard 63 rigidly mounted on the shaft 57 and on the rod 64, and when the gate is in such closed position the spirally arranged. spring-controlled, pivote carrying pawls (i5. which are mounted on the lower part of the yoke 43. are prevented from engaging the teeth of their ratchets 58 when the yoke or frame is on its return stroke. Vhen, however. the gate is opened or actuated. the pawl 65 will engage the ratchet 58 and rotate the same one-tenth of a revolution. which. as will be obvious, will rotate the major gear with which the transfer wheel engages, a corresponding amount. The gate and gateactuators are of course operated during the Also mounted on the shaft 57 down stroke of the yoke or frame 43, and the carrying or transferring is accomplished on the return stroke, and it becomes necessary to keep the gate open until the gear pawls 65 have had opportunity to operate the transfer wheels, and such means are provided in the spring-controlled, piyoted, gate-actuated, controller 66, the latter being supported on a transverse fixed rod 67. Said controller is provided with a projecting flange. 68 which is adapted to catch beneath a cooperating, projecting flange 69 formed on the gate-actuator 54 when the latter has been operated by a projection 52,

and adapted to hold the gate-actuator against the tension of its spring until after the transferring or carrying operation has taken place. Said controller may be released in one of two ways, either by the yoke or frame 43, which, on its return stroke, engages a depending projection 70 on the controller, or by means of the canceling or clearing bar 4l, which is adapted to engage a cam face 7l also formed on the controller 66, the latter operation taking place during a canceling stroke only. In order to pre'- vent overthrow of the transfer Wheel during the carrying operation, a detent 72 (Fig.

28), yieldingly controlled by a spring 76 isA provided, which is in the form of a disk .pivotally mounted, as at 73, on the bracket 63, said detent being provided with a slot 74 for clearing the shaft 57, and having also a projecting lip 75 movable in a slot 75 in the bracket 63 (Fig. 29) and which engages the ratchet 58 of the transfer wheel when said detent is moved against the tension of its spring by means of the coperative carrying dog 65 that engages a cam face 77 thereon. The cam face 77 extends a little over the forward part of the opening 62 whereby the detent 72 will be held in engagement with the ratchet 58 for an appreciable time after the carrying dog 65 has passed by the opening G2 which will provide sufficient time for the shock on the transfer wheel to he dissipated, thus preventing overthrow of the transfer wheel, said cam face 77 operating finally to disengagc the carrying pawl from the transfer devices as the return stroke of the yoke is continued.

@Zeer/ng or canceling flnfa'ns'r-ll'hen all the sums desired have been accumulated on the register wheels. and no further additions are to be made. the set-up levers will of course all he at normal and the sum accumulated on the registerwhcels can he canceled hy oscillating the yoke or frame 43. When all the set-up levers are at. normal, all the clearing har pawls 38 will he in their -lowered or normal position which will althereby rotating all of the disks andthe gears connected therewith to a position where the register wheels will all indicate zero.v )When a printing orlistening mechanism is combined with the adding mechanism, as hereinafter described, the total accumulation of the adding mechanism will ordinarily be printed before the clearing or canceling operation is performed.

Means ,for disconnecting the set-up levers from the prime-actuating mechanz'sm.-In practice, it is found that the operator occasionally makes an error in setting up the setup levers, and it is desirable to correct such error without the necessity of canceling the amount which may be already accumulated such means -in vthe on'the register wheels, and I have provided following devices. Mounted between each set-up lever disk and major gear is a releasing lever 78 (Figs. 9 and241) which is in the form of a disk `keyed lto the shaft 429, the latter extending to the outside of the casing, and having a crank arm 79 by which the shaft may ybe oscillated. as desired. Each lever is eXtend ed' at.78 so as to come between the pawl orpawls 32 on the set-up lever 30 and the atchet v28 so that when the lever 7 S is rotatedf forward, its lower portion turning backward,'the same will release-the pawl or `pawls from` the ratchet.

" lever is thus disconnected the extended part While the set-u p i ofthe release lever vengages a projection 80 i' formed on'the 'set-up lever disk, whereby. the latter is returned to normal withoutactuati'ngtheratchet 28,.and thereby the gear 27 sffprvevent'ejd, .from actuating its register 1.--`.Thee1e ase levers 78 are normally inoperative position by means ecu'red to the left-hand end of heiipp'enpartf of the diskl 81 rearer-ringfagain' to 'the lplatev 48 and the ctions49 thereom'it will be seen that Iatter, by engaging the ratchets 26, will .locl'r1the register wheels and prevent. the

i same from being-operated by attempted manipulations ofthe set-up levers independent of the oscillatable yoke.

Such being the construction and' arrangement of the adding mechanism, which is or may be ofthe same construction and mode of operation as that set forth in my pending application, filed Oct. 25, 1912, Serial No; 727732, I will: now proceed to describe the printing or listing, and totalizing mech anism and its connected parts, which are' combined to coperate with the said adding mechanism.

The printing or Zz'stz'ng mechanism--97 indicates the type bars arranged preferably at or near the upper or rear part'of the machina to be impressed against a sheet of (Fig. 3), said disk 81 having on'V I,cted.there,witha spring 82 arranged to paper fed around the inner side of the papel roll 98, this roll being mounted upon a shaft 99 carried in the frame 23.- The type v bars` are formed on their rear faces with type 100 (Fig. 22) so 4arranged that the uppermost type will print 0, the next lower type will print 1, etc., the lowermost type printing 9. I find it convenient to arrange these 10 types on 5 type bars, 2 types on each bar, but they are so adjusted up and down by' the operation of the adding mechanism (or of the totalizing mechanism) that only one type in each vertical row will print at once upon the paper. The type bars 97 are mounted in a type carrier 101 so as to be capable of having horizontal motion therein toward and from the platen roller 98, being advanced for printing by the blows of a suitable hammer, and being retracted to normal position by springs 102 (Fig. 1). Each type carrier 101 is or may be constructed of several parts connected to forma unitary whole, the lower portionl of which extends down toward the base of the machine. 103 indicates bearings formed with or attached -to the type carriers (Fig. 9) and arranged This wedge is caused to engage the type can riers for alining them, and is, after printing, removed from engagement, by suitable mechanism hereinafter referred to. The type carriers' are constantly drawn downward by springs 107 (Fig. 13) connected with the carriersl at 108 and attached to the frame 23by means of a cross-rod 109 (Fig. 8). 110 indicates racks, one of which is attached to each type carrier and is engaged by a gear 111 mounted loosely on a fixed shaft 112. The rack 110 is made adjustable on the type carrier in order that the type carriers may be initially adjusted to a proper normal position relative to the operating gear 111, and to this end the type carriers'may be vertically adjusted relative to the racks 110 by means of an eccentric 113 (Figs. 14 and 15)', which eccentric is mounted by'bearing pin or shaft 114 on the typecarrier 101 and engages with a lug or shoulder 115 which is connected with the rac'k 110 through. a slot 110 formed in the type carrier. A slight turning of this eccentric moves the type carrier verticallyv relative to the rack. 117 is a pinion attached to the gear 111 and meshing with a 130
